Move Actor along landscape spline?

So I know how to do this with a normal spline, but what about a landscape spline? Surely this is a thing… I’ve made a railway track and I want to make a train mesh move along it.

Is there even a way to duplicate/convert a landscape spline to an actor spline so I can do it the normal way?

Hi, you can only access the landscape splines from c++ as far as I know.

I’ve built a tool into rdSpline tools that copies them into BP splines, but I haven’t released the update yet. It’s pretty straight forward.
